When Jews were kicked out of Spain, they went west to Portugal. Soon after, when they were kicked out of Portugal... there was nowhere left to go. If you haven't noticed, there is only one way out of Portugal, and that was back through Spain. That wasn't going to fly.

So Portugal's Jews thrust their sights on the seas. Some went to Amsterdam, some to America, some to Cape Verde, a Portuguese archipelago off the coast of Africa. In fact, one island served as a penal colony for Jews. (The Portuguese were ahead of their time...) Eventually, the Inquisition made its way to Cape Verde, so that was the end of that. Even the marranos eventually had to assimilate.

Today, the Jewish population of Cape Verde is virtually non-existent. Interestingly, the extensively-named Carlos Alberto Wahnon de Carvalho Veiga, who was the now-independent country's prime minister in the 1990s, does have a Jewish background. His grandparents emmigrated from Gibraltar.
